PCR products from Wednesday's PCR. Lanes 2 - 3: Fluoride riboswitch biobrick genomic DNA. Lanes 4 - 5: MGRS construct genomic DNA (+8). Lanes 6 - 7: MGRS construct genomic DNA (-8). Lane 8: MGRS biobrick genomic DNA (+8).
PCR products from Wednesday's PCR. Top: Lane 2: MGRS biobrick genomic DNA (+8). Lanes 3 - 4: MGRS construct backbone (expected size 9kbp) (+8). Lanes 5 - 6: MGRS construct backbone (expected size 9kbp) (-8). Lane 7: MGRS biobrick vector (+8). Lane 8: Positive control. Bottom: Lane 2: MGRS biobrick vector (+8). lane 3: Negative control.

PCR of biobrick fragments and MGRS construct fragments.


  • Fluoride and magnesium riboswitch genomic DNA amplified with PCR, along with vector fragments for turning the MGRS into a biobrick and for producing the magnesium riboswitch construct.
  • PCR settings: Annealing temperature - 58 °C, Elongation step - 60 seconds.
  • Genomic fragments worked well, but longer backbone fragments mostly failed.
  • Extractions of DNA from these gels failed almost completely. Will try purifying directly from PCR products next time - results may not produce such a high purity of the precise DNA we want, but the increase in yield should outweigh this problem.
